Unswitchable cassette belt

[Jackieman]

Hi, I just got a boombox I’ve been tinkering with working, but I got one last problem. The belt inside is too loose. Common problem, but the issue is that I can’t change it. It’s as deep into the thing as it can possibly be. I will never be able to change it without cutting cable to take it completely apart and I REALLY don’t want to do that. Any tips if there is any at all on how I could tighten the belt without taking it out?
EDIT: The model name is Sanyo MGT 7

Welcome , it would help if we knew the model of the boombox , might take some work but that's the only way to really fix the problem.

It’s a Sanyo MGT 7. It’s stunningly beautiful, so I really wanna get it working.

Well it's all switchable, although like you've observed, some are easier than others. As to your question, the answer is no, you can't "tighten" a belt. If it's loose, the only fix is to replace it.
